Readback buffers are allocated when the readback is recorded rather than on the render thread, so only the thread that records frames touches VMA. The allocator is created externally synchronized, and VMA is built with no-op mutexes and plain counters instead of std::mutex and std::atomic. Headless runs Vulkan offscreen in builds without SDL too, and CI runs the headless tests on lavapipe, skipping the pixel tests a hardware backend doesn't match the software references on. sleep_ms and sleep_us go, with the thread manager test waiting on an event instead, and so does the unused portable-file-dialogs header.
